WINDOW-FRAME.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed March 31, 1906. Serial No. 309,178.

Be it known that I, ERNEST BAUER, a citizen of the United States, residing at Milledgeville, in thecounty of Carroll and State provision of'a supplemental frame, a portion of which can be swung inwardly with the sash supported therein, so as to permit the cleaning of the outside of the glass. The manner of construction and specially advantages to be derived from the use thereof will more fully appear in the following specifications, reference being had to the accompanying drawings, in which Figure 1 is a vertical section of a window embodying my invention, with the parts thereof in their normal position. Fig. 2 is a similar view with the lower sash swung inwardly into the room. Fig. 3 is an enlarged detail showing the means of fastening the guide frame 8.

Similar numerals refer to similar parts throughout the several figures.

1 is the usual frame of the window and 2 the sill thereof. frame is secured a guide frame 3, extending outwardly to the strip 4. The guide frame 3 is held in place by a screw 5 in the upper part thereof, and a thumb-screwpassing through a curved slot 7 in the guide frame 3 and into the frame 1 in rear thereof. A similar guide frame 8 is swingingly supported from the guide frame 3, by means of a circular guide frame 9 on the upper end of the guide frame 8, pivotally secured to a similar guide frame on the lower end of the guide frame 3, as at a. Said pivotal point is in line with the inner edge of the guide frames 3 and 8 when such guide frames are in contact, as shown in Fig. 1.

Channels 11 and 12 are provided in the faces of the plates 3 and 8, such channels being continuous when said guide frames are in line, and forming means of support and vertical movement for the lower sash 13 and upper sash 111, respectively. The lower guide In the upper part of the frame 8 is held normally closed, as shown in Fig. 1, by means of one or more keys 15, eX- tending through the uide frame 8, and through a slotted guide ame 16 in the frame 1 into a recess 17 in rear of such plate. A partial turn of the key locks it from removal.

When closed, the outer edges of the guide frames 3 and 8 are in contact with the strip 4,- preventing the entrance of rain between such parts. The adjacent ends of said guide frames also meet closely, preventing the passage of moisture between them. The lower end of the guide frame 8 is just above the sill 2, and the outer corner thereof is rounded to permit the swinging of the guide frame 8 inwardly.

Vhen it is desired to clean the outer face of the glass in the lower sash the keys 15 are released, the sash raised until the lower edge thereof clears the sill, and the guide frame 8, sash 1'3, and corresponding guide frame at the other side of the window, (not shown) swung outwardly as shown in Fig. ,2. It is preferred to swing the sash outwardly until it is in a horizontal position, in which position it can be supported in any suitable manner while the glass is being cleaned. After the lower sash is cleaned, the guide frame 8 can be returned to its former position, and the sash 13 moved upwardly into that part of the channel 11 in the guide frame 3, where `1t can be secured. The sash ,14 can then be lowered into the guide frame 8, and swung outwardly therein, to be cleaned, similarly to the sash 13.

' When the guide frame 8 begins to move outwardly there is a tendency of the outer corner on the upper end of said plate binding slightly against the strip 4, but this may be provided against by. first loosening the thumb-screw 6, whereby the lower end of the guide frame 3 is permitted sufficient movement inwardly to prevent any interference of said parts, the upper edge of the guide frame 3 being beveled rearwardly to permit such movement of the frame without interference with the top of the jamb.

The guide frames 3 and 8 are preferably formed of metal, and the device can easily be placed in'position in old window frames, by trimming a small portion from each side of the sash.

While it is specially designed to be used in cleaning the glass, my invention can also be employed for the removal of the lower or upper sash, if desired for any purpose. Byhav- IOO IIO

ing the pivotal point between the guide frames 3 and 8 near the inner edge of such guide frames the lower guide frame 8 is projected a greater distance into the room, when open, such guide frame being almost entirely within the room when in a horizontal position. There is also less tendency of the parts to interfere or bind, as the upper end of the guide frame 8 is moved at once inwardly, describing a segment of a circle.

By means of the pivotal guide frames 9 and 10 greater strength is given to the parts, and turning or twisting of the guide frame 8 while supporting one of the sashes, is prevented.

In the case of a window extending nearly to the floor the guide frames 3 and 8 can be reversed, the stationary guide frame being secured in the lower part of the frame, and the movable part being above, and opening inwardly and downwardly.

In cleaning the upper sash 14, such sash is lowered into the guide frame 8 until the lower end thereof is no lower than the end of the guide frame 8, so as to permit the sash to move freely over the sill 2. In this position the upper end of the sash 14 will project a short distance above the upper end of the guide frame 8. To permit the free movement of the upper end of the sash as the guide frame 8 swings outwardly it is found necessary to discontinue the track l2 for a short space on the lower end of the guide frame 3 by cutting away the strips which deiine the same.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

l. A device of the character described, complrising an upper and a lower guide frame in w ich the window sash are slidingly supported, the upper frame being pivoted near its upper end in the upper half of the window j arnb, means permitting a slight swinging of the said Jr'rame on its pivot, the lower guide frame being pivoted at its upper end t0 the upper guide frame at a point in line with the lower end of the upper guide frame to swing' inwardly, and means for locking said frames in vertical alignment.

3. A device of the character described, comprising a guide frame comprising upper and lower sections hinged together at their adjacent edges, said guide frame being 'pivoted adjacent its upper end in the window jamb, the lower section being capable of a greater inward movement than the upper section, a sash arranged in each section, the upper sash being removable from the guide frame when the lower section is swung inwardly.

4. In combination with a window jamb provided with a bead strip adjacent its outer edge, a guide frame comprising upper and lower sections arranged in said jamb in close proximity to said bead strip, the lower of said sections being pivoted at its upper edge to thelower edge of the upper Section and capable of inward movement, and means permitting limited movement of the lower end of the upper section permitting the upper edge of the lower sectlon to clear the bead strip when said lower section is swung inwardly.

In testimony whereof, I afliX my signature, in presence of two witnesses:

ERNEST BAUER. Witnesses:
